Abstract: A booster seat has provisions for accomodating a child in a number of different height positions. The booster seat comprises an open-sided base and a seat piece. The open-sided base has a forward channel and a back channel in each of two side supports. A seat of vertically spaced substantially level ledges are found in the channels, vertically offset from one another. The seat piece has a forward protrusion and a back protrusion on each side edge. The protrusions are vertically offset a distance substantially equal to the offset distances between the ledges so that when the protrusions engage the ledges in the base, the seat piece is substantially horizontal and secured in the open-sided base.

Abstract: A baby-feeding bottle convertible between one of larger capacity, e.g., ten fluid ounces, and one of smaller capacity, e.g., five fluid ounces. A lower part and an upper part when assembled to each other, at a threaded connection, provide a container of larger capacity. The lower part is useful, as a container of lower capacity, without the upper part. A collar is useful to mount a pliable nipple on either part. The threaded connection is peripherally covered by an annular rim, which is integral with the upper part, and which substantially conforms to an outer wall of the container provided by the lower and upper parts assembled to each other so as to present a substantially uninterrupted gripping surface to a user.

Abstract: A baby feeding bottle assembly in which a four ounce bottle may be converted to an eight ounce bottle and providing improved means for easy gripping of the bottle assembly by an infant or small child. The baby feeding bottle assembly is elongate and includes two parts. One of the parts may be a baby bottle of a four ounce size, and the other of the parts may be a threaded adaptor having threads at each end so that one end may be secured to the bottle and the other end may be secured with a feeding nipple. When assembled, the assembly defines a generally dumbbell or hourglass configuration generally centrally of the elongate assembly for facilitating gripping by an infant or small child.
